Modèle d'accrétion de glace sur un objet bidimensionnel fixe appliquable aux pales d'éoliennes
Published 2004-05-01“…The roughness height depends on the surface water state, which can exist in the form of a film, bead or rivulet and is calculated from the equilibrium equation between the surface tension, aerodynamics and gravitational forces acting over the bead. Residual, runback and shedding water masses are calculated using analytical models based on the roughness height and the new surface position is calculated using a geometric method based on the bisection between the defining panel's surfaces. …”

Different Magnetic Field Distributions in Deformed Neutron Stars
Published 2019-04-01“…The second formalism for investigating macroscopic properties of magnetars is gained by treating the nonuniform pressure as a perturbation to the total pressure and expanding metric and pressure up to the quadrupole term in spherical harmonics.Afterwards, we include three nucleon interactions (TNI) to the EoS and apply this model to represent our results for both exponential and polynomial magnetic field profiles.The maximum gravitational mass is obtained in the range of (1.71-1.80) M. and (2.13-2.19) M. for the EoS without and with TNI contribution, respectively.…”
